Thats just his stance, it allows him to see whats coming and he tucks his chin in so he dont get rocked. But the stance alone wont help you..lol..I can have a stance like Bruce Lee and get the snots beat out of me..becuase im not him, Floyds defense is his ability to see punches come and is really quick and knows how to roll with shots and know exactly where to stand to counter its years and years of practice.
